We take a critical view of the standard approach to finance and growth. The mapping between the theory and empirics is shown to be poorly understood, and this is traced to deficiencies in our understanding of the microeconomics at play. By looking at both primary and secondary historical evidence we argue that issues of aggregation are critical, and that spatial factors are also prevalent. Further, we suggest that these disaggregated elements can change over the course of an industrial revolution. A model in the spirit of standard finance and growth theories is extended to consider these further effects, and we calibrate the model to data on historical growth paths. In order to advance our understanding of the microeconomic factors that cause the observed phenomena in the finance-growth nexus, we develop a general equilibrium theory of financial intermediation in which exchange costs are endogenously determined by technologies, endowments and preferences. We suggest that incomplete contracts might be central to these phenomena. We link this framework to an understanding of power and political economy in a setting with heterogeneous agents. We develop these results numerically, showing a number of interesting interactions between markets, exchange costs and institutions in economies with different levels of wealth. The model of endogenous exchange costs can be thought of in terms of the findings coming out of our historical analysis. We outline in some detail the further steps that need to be taken before we can speak of the microfoundations of finance and growth with any confidence. First, a fully dynamic model of markets and coalitions must be embedded within a story of economic growth that can match the dynamic observations. Second, we must develop our conception of incomplete contracting and the link with institutions and political economy. The thesis thus opens a number of interesting avenues for future research.

AbstractThis paper proposes a simple model for understanding transaction costs – their composition, size and policy implications. We distinguish between investments in institutions that facilitate exchange and the cost of conducting exchange itself. Institutional quality and market size are determined by the decisions of risk adverse agents and conditions are discussed under which the efficient allocation may be decentralized. We highlight a number of differences with models where transaction costs are exogenous, including the implications for taxation and measurement issues.

We study the local impact of foreign aid allocated to districts and constituencies in Malawi over the period 1999–2013 using a highly detailed new aid database that includes annual disbursements at each project location. First, we show using household panel surveys that growth in light density is a good proxy for growth in per capita consumption. Second, we introduce a new dataset that permits a novel instrumental variables strategy. We find a consistent and quantitatively significant relationship between aid and growth. Constituency-level regressions point to a larger effect than at district level, suggesting that aid is associated with some relocation of activity across space but not enough to make the net effect zero. The effect on growth is at its highest immediately after its disbursement, and falls to close to zero in subsequent years, implying that foreign aid has a level effect on incomes but does not stimulate sustained growth. Aid delivered as a grant is positively related with growth, while that given as a loan is not.

AbstractThe equilibrium size of a nation state is, in part, the result of a trade-off between the gains from scale economies in the provision of public services and the costs of applying uniform policy to heterogeneous cultural, institutional and geographical fundamentals. Changes in such fundamentals can thus place pressure on states to reform over time. We consider this dynamic state formation process in the context of Scotland within the United Kingdom. First, we review the recent research in economic history on the persistence and evolution of such fundamentals. Second, we consider the history of Scotland both before and after the 1707 Act of Union in the light of that broader economic history literature. We conclude with some implications of fundamental persistence for current debates on the place of Scotland within the United Kingdom.
